PRIMING DEVECE FOR GHSOLENE-ENGINES.

Application iiled November 14, 1917.

To all whom it may concern:

Be it known that l, PAUL Smarrita, a citizen of the United States, residing at Nampa, in the county of Canyon and State of Idaho, have invented 'certain new and useful Improvements in Priming Devices for Gasolene-Engines, yof which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved priming device for gasolene engines employed for the production of motive power in connection with various classes of `vehicles, such for instance, as automobiles, aeroplanes and the like. y

It is a primary object of the invention to provide simple and effective means -under the instant control of the operator for supplying a priming charge of the motive fuel in a finely atomized state directly to the cylinders of the engine.

It is another and more particular object of the invention to provide a priming apparatus for the above purpose embodying a pump including "a cylinder connected to a pressure receiving tank, a manually operable valve to open communication between the tank and a source of vfuel supply or between the tank and the atmosphere, and an Aadditional -manually operable valve 'to control the supply of pressure fluid jfrom the tank to the priming cups of the engine cylinders.

It is another one vof the detail objects of therinvention to provide'an improved construction o'f 'the release valve for the priming charge and means for operating sai valve from 'the dash *or instrument board of the vehicle.

And it is a further general object of the invention to improve and simplify apparatus 0f the above character, rendering the same highly efficient and positive in its operation, and capable of manufacture at comparatively small cost.

Vi'th the above and other objects in view, the invention consists in the improved combination and arrangement of the several parts to be hereinafter particularly described and subsequently pointed out in the appended claim.

Figure l is a side elevation disclosing one embodiment of my invention and showing the same mounted upon the vehicle dash;

Fig. 2 isa vertical sectional View through one end of the pump cylinder illustrating the valved connections to the pressure tank and the gasolene supply;

Fig. 3 is an enlarged sectional view through the release valve taken on the line 3 3 of Fig. l; and

Fig. 4 is a face view 'of 'the key plate mounted on the vehicle dash or instrument board.

Referring in detail to the drawing 5 designates a pump cylinder which, in thev illustrated construction, is connected to a iiange or boss 6 projecting from one face of the key plate 7 which is secured upon the tank or instrument 'board D with which 'the vehicle'is equipped. To the other end of this cylinder, a hollow head 8 is detachably connected by means of a threaded coupling sleeve 9. 'This head is provided at diametrr cally opposite points with nipples il() and ll respectively. rllhe nipple l1 is provided with a valve seat lf2 lupon which ther valve ball 13 is normally engaged. bushing 14 has threaded engagement in the nipple and lim-its the movement of the valve ball i3 from its seat. This'nipple is c0nnected 'bythe pipe 14 'to a pressure receiving tank 1(not shown), mounted at any convenient point upon the vehicle body. y

A bushing 116 is likewise threaded in vthe *seat 17 formed on one end to receive the valve ball 18. The displacement of said ball from its seat is limited by the shoulder 19 Lformed in the bore To the f ipple l0 a 'valve `casing 20 is connected, 'an' in the casing a rotatable valve -plug 21 is engaged. This plug is formed with a transverse port 22 and `an ori'lice 23 extending at right angles to this port Acommunicates with Ione side of the port and 'opens upon the periphery fof the valve plug. Thecasing 20 is provided with a lonlgitudinally extending passagev 24 in communication with the bore olf the nipple l0. Gasolene is delivered from a suitable supply tank to the other end of this passage through the medi-um of a pipe or tube y25 which is connected to the casing 20 by means of a 'coupling sleeve 26. The casing 20 is additionally provided with a transverse port or A sleeve yor site direction, the

longitudinally the passage 24 through thel medium of the port 22 and orifice 23 of the valve plug. Thus the gasolene supply is cut off and in the continued operation of the pump, air is drawn into the pump cylinder. Y

The valve 21 may be conveniently operated by means of a rod 27 operatively connected at one of its ends to the valve member and having its other end extending through the idash D and rotatably mounted inthe key plate 7, a suitable head or fingerV piece indicated at 28 being fixed to the latter end of the rod.

The piston 29 which reciprocates in the pump cylinder 5 is operated through the medium of a vrod 30 which extends through the head on the end of the cylinder mounted in the key plate 7 and is equipped with a suitable hand hold indicated at 31. It will of course,.be readilyseen that in the movement of the piston 29 in one direction, either' gasolene or air is drawn into the cylinder past the valve 18, in accordance with the adjustment of the valvel plug 21 and in the movement of the .pumppiston in the oppofluid is forced underpressure fromthe cylinder through the pipe connection 15 to the pressure receiving tank.

The cylinder head 8 is formed on its end face with a T-shaped enlargement or projection 32, the vertical portion of which is bored as at 33 and provided at its lower end with a' threaded nipple 34 for the connection thereto of the pipe or tube 35. yThen the engine is provided with -a double row of cylinders, a T-coupling may be provided for the connection of tubes 35 to the bore 33. The horizontally disposed portion of the enlargement 32 oir the cylinder head has abore 36 in one end thereof to which the pipe 37 extending from the pressure receiving tank is suitably connected.

At the other end of lthis bore 36, a valve 40 has threaded engagement as at 41 in the opposite end of the horizontal arm` of the enlargement 32. A threaded opening is provided above the needle valve andv in alinement with the bore 33, said opening being normally closed by means of a plug 42. Thisopeningis provided for permitting convenient access to the bore or passage and the purpose of cleaning the tank.

' To the outer end of the needle valve rod 40, a downwardlyextending curved arm 43 is lixed. This arm is recessed in concentric relation to the valve rod to receive one end of the coil spring 44 looselysurrounding said rod, the said end of the springL being fixed to the valve rod. The `other end of the spring isl secured to a pin indicated at 45 projecting fromthe cylinder head 8. The arm 43 is actuated by means of a rod 46 connected to the other end of said arm and extending in parallel relation to the pump cylinder 5 through the dash board and the key plate 7, said rod being provided on the latter end thereof with a finger button or head 47. Normally, the spring 44 act-s to hold the valve rod against turning movement with the needle point 39 of said rod engaged upon the seat 38, thus closing communication between the vertical bore or passage 33 and the pressure tank. W'hen it is desired to open this valve to release a priming charge into the pipe or tube '35,* the button 47 ispressed to force the rod 46'longitudinally, and thereby swing' the arm 43 to rotate the needle valve 40 against the action of the spring 44. In this rotation of the valve rod, owing to its threaded connection with the part 32, said valve rod will shift longitudinally and the needle point 39 thus be moved away from the seat 38. The air pressure in the pressure tank, actingupon the gasolene, breaks the same up into minute particles and immediatelyvupon the opening of the needle valve, this atomized gasolene is forced under pressure through the passage 33 and into the pipe or tube 35. d

1n the accompanying drawing, I have illustrated a coupling v48 adapted to connect a goose-neck pipe 49, which is 'suitably connected lto the pipe or tube 35 to the priming cup of one of the engine cylinders. It will of course, be understood that one of these couplings is provided be-` tween each enginefcy'linder and thepipe 35. Each 'coupling 48 preferably includes a spring pressed vvalve rod or pin indicated at 50 which normally closes communication between the priming cup and the pipe or tube 35, said rod being engaged at its lower end upon the valve seat indicated at 50. This valve rod may be of any suitable' form and construction,but as illustrated-it is of slightly less diameterfthan the coupling member connected ltothe priming cu through which said rod ext-ends, so that the fuel will be delivered in radial directions in its atomized condition lintothe priming cup and thence to the engine cylinder. A

From the foregoing description taken in connection with the accompanying' .drawin the construction, manner of operation andF several advantages of my invention will be clearly and fully understood. is 'rst adjusted :so/.that upon the operation of the pump piston, gasolene willbe supplied to the pressure tank, and by then turning the valve 21 as indicated, air is drawn into the pump cylinder' and forced into the pressure tank where it impinges upon the gasolcne and breaks the same up into a spray. One operation of the pump in this manner is sufficient to supply the tank with several priming charges for the engine cylinders. Upon now operating the needle release valve s0, the priming charge of atomized gasolene is immediately supplied directly to the engine cylinders so that the engine may be immediately started, even in severely cold weather. By means of my improved priming apparatus, all danger' of overcharging or flooding the engine cylinders, as is frequently the case when the carbureter is Hooded, will be obviated. As the pump and the several valves are operable from the dash or instrument board of the vehicle, the operator is not Irequired to leave his position and he may at any `time ascertain, by the operation of the primer whether or not the carbureter is in good working condition.

The invention as herein described, consists of relatively few parts which are of simple form and construction so that the entire apparatus may be produced at relatively small manufacturing cost and installed upon automobiles, aeroplanes and other motor driven vehicles without necessitating any material structural alterations in the vehicle. The foregoing disclosure has relation to one embodiment of the invention which I have found to give very satisfactory results in practical use, but it is to be understood that in the adaptation of the priming apparatus to various types of vehicles, certain Copies of this patent may be obtained for ve cents each, by addressing mechanical alterations may be required. Therefore, While I have herein shown and described a certain form, construction and arrangements of the various elements, the same are nevertheless susceptible of considerable modification, and I accordingly reserve the privilege of adopting all legitimate changes which may fairly be considered within the spirit and scope of the invention as claimed.

I cla-im:

In a priming apparatus for internal combustion engines, a pump including a cylinder and piston operating therein, said cylinder having a head on one end, a connection between said cylinder head and a pressure receiving tank, a manually operable valve connected to said head to open communication either between the cylinder and a source of fuel supply or between the cylinder and the atmosphere, said cylinder head being additionally provided with aI passage, a supply connection leading from the pressure tank to said passage, a valve normally closing communication between said supply connection and the passage, a conduit connecting said' passage to the several engine cylinders, and manually operable means connected to the valve to open the same and release a priming charge into said conduit.

In testimony whereof I hereunto affix my signature iu the presence of two witnesses.
